The gifs below demonstrate a few of the bicycle's features, including removing, using, and replacing the lock, and raising and lowering the bicycle's seat.
To take the lock off the bicycle, push the button on the side and pull. Push the lock into the holder to replace it.
Pull back on the silver lever below the seat. Pull up to raise the seat, and push down to lower it. Lock the seat in place by making sure that the silver lever is firmly closed.
